Abstract

This paper presents the 7-level H-bridge cascaded inverter for renewable energy source. The inverter based on 3 H–bridge single phase inverters that are separated is connected in series. The inverter is supplied from the dc source. The control circuit using Sinusoidal Pulse-Width Modulation (SPWM) technique with PD for controlling switches in the inverter. The control signal generated by Digital Signal Processing (DSP) #TMS320F28335 processor with MATLAB/Simulink is provided for 12 SPWM signals to output port. The 7-Level H-Bridge Cascaded Inverter can generate the output ac voltage 180 Vp from dc voltage source and can be measured the total harmonics distortion (THD) with varies modulation index (ma). The simulation results obtained from the MATLAB/Simulink program have confirmed the proposed circuit.
